limited (for now ) by what subject matter can be rendered in 1/30 second
or less. Don't confuse that with projector resolution or image quality on
While I would agree that video on the dome is not up to film quality...
yet... I would have to admit that it is a whole lot closer than I thought
it would be. The Barco 1209 series projector is being discontinued at the
end of this year. It will be replaced with a model called the BR909. The
resolution of the BR909 is 3200x2560. If you put six of those projectors
on the dome at full resolution you will have a full color star field that
you can fly through. You and I could, probably, still tell the difference
between that and a Zeiss. However, I'm willing to bet that your audience
won't be commenting about the star field quality as they exit the theater.

video AND a star ball in their theater. Ask a vendor that does not sell
star projectors the same question and see what they say.
